1 Scope This European standard specifies the characteristics of spherical plain bearing in corrosion resisting steel, with self-lubricating liner, narrow series, for elevated load. at ambient temperature, with or without swaging groove, intended for use in the fixed or moving parts of the aircraft structure and con- trol mechanisms. They shall be used in the temperature range −55 °C to +163 °C. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

4 Required characteristics 4.1 Configuration, dimensions, tolerances and mass According to Figures 1 and 2 and Table 1. The dimensions are expressed in millimetres and apply after surface treatment. 4.2 Surface roughness According to Figures 1 and 2. The values are expressed in micrometres and apply before surface treat- ment.
6 Marking According to EN 2424, style A. The marking position is at the manufacturer’s option. Bearings ordered without technology code shall be delivered marked with the code of technology used. 7 Technical specification According to EN 2755.
8 Quality management system The manufacturer’s operations shall be an approved production organisation for aerospace products and shall demonstrate that it has implemented and is able to maintain a quality management system (e.g. according to EN 9100 or an equivalent aerospace accepted and established quality management system). The qualification procedure for aerospace standard products (e.g. according to EN 9133 or an equivalent aerospace accepted and established qualification procedure) shall be used and documented according to the specified tests if not otherwise agreed between customer and supplier.BS EN 2584 pdf download.
